the cylindrical end portionl of an arm 16'. For this purpose, the head 11 is provented al new and Improved Chirographicy Reproducing-Machine, of which the follow-v ing is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: To provide a machine for mechanically reprgduc-l in an exact copy of signaturesor other chirographic productions; to provide individual mechanical records for controlling an apparatus of the character described, to individualize the product thereof; to provide a machine adapted forfmechanical'writing when operated by individualized'and suc.`V

cessively-installed records;` to vprovide la may,

chine of the character mentioned with a marking tool, variable .by pressure applied'v thereon, and means for controlling. said pressure, mechanically identified with the chirog.- raphy being reproduced; to provide a' ma- 'chine of the character mentioned,operably controlled by mechanical idiosyncratic -records; to prov-idea machine ofthe characterA mentioned, having automaticy controls for holding in fixed relation the paper preliminary to imparting thereto-the chi'rogiaphyfh produced by said'machine; and 'to' provide means for varying the .direction ofthe operation of the markingimplement tol simulate4 the movement of the human hand and--wrist of a machine constructed and arranged in v accordance with the present invention, the

vvided with a reduced section 17, which is rig.- ldly mounted on a rocking shaft 18.

.The holder 13 is provided with a collar 19,

said vcollar having a spur 20 to extend in serv-ice within the slot formed by the opening of the sides of the head 11. In this man- 4 ner the pen may be always returned to its service position after having been released by andy removed, from the head 114 for the /purposeof filling or repair. i

The rockingshaft 18, as best shown in Fig. 2 of the drawings, is extended through the arm 16,"and is supported in bearings 21 .and 22 therein. At the inner endof said shaft an extension 23 is engaged by a con- Anecting rod 24. The connecting rod 24 issimilarly-attachedvto an extension 25, with which fa second rockingshaft 26 is furnished. The rocking shaft 26 is mounted in bearings .formed in short standards 27 and 28, flxedly -mounted on'a movable platform 29, r Extending ina' substantially vertical* direction frOm, and rigidly attached to the shaft`r2p6, 1s an arm 30, to which is pivotally connected a connecting rod 31. As seen bestv inFig. 3 of thedrawings, the rod 31 exi tends horizontally, and is pivotally attached to .an arm 32,. which corresponds with the arm. 30 and is normally disposed parallel thereto. The arm 32 is rigidly connected with a shaft 33,1which, as show-n best in Fig.' 2 of the drawings, is mounted in bearf Drawings--Figure 1- is atop plan view inglbrackets 34v and 35,"rigidly secured to 1 and pendent from a table 36. The above dewhere necessary, to show the interior Aar` rangement thereof; Fig. 3'is a fragmentary lview with portions of the'mechanism omitted. Fig. 4 is a detail view in plan, showing an example of the operation of the linetracing member.

Description-As seen in the accompanyscribed mounting of the lshaft'33 definitely locates the working position ofsaid shaft, i and the flexible connection V`between said.

shaft' 33and the shaft 26 formed by the rod 31, permits the relative swing of' the shaft 26 when the platform 29 is moved;

The purpose in the above-described construction is to permit a variation of pressure v to be.imposed on the pen 14. To this end,

` the' shaft 33 is rocked by a crown cam wheel 37, the upper edge whereof is undulated, as 4 ing drawings, a writing pen is held in aclamp head 11.` The head 11 is expansibley and contractible, by-means of a screw'12,

Lon the barrel or `holder 13 of a'writing pen 14. The pen employed by me is preferably of the type known as fountain pens. The

clamp head 1l is arranged to fit snugly withbest seen in Fig. 2 of thedrawings. Rest! ing on the undulatin edge of the wheel 37 is a .roller 38 mounte on the free end of a crankarm 39. The crank arm 39 is fixedly attached to the shaft 33 to rock the same in sympathy with the movement imparted by .the cam wheel 37 to the free end of said crank arm. The undulations of the edge of the wheel 37 are platted to correspond with the pressures upon the pen used in forming the original from which the copies are made. Coincident with the platting of the undulated edge of the cam wheel 37, the undulations on the cam wheels 40 and 41 are also platted in the manner vas hereinafter set forth.

The platform 29 is movably mounted on a polished bed plate 42. The supports for the platform are felt pads or plugs 43, which are mounted in cups 44 to rest each under a bearing plate 45. The plate 45 is adjusted by means of a feed screw 46, a lock nut 47 being provided for each of said screws, to hold the same in adjusted position. The screws 46 are particularly useful for truing or leveling the platform 29.` Said platform, arm 16, shaft 26, and parts connected therewith, including the pen holder 13, and pen 14, are shifted by levers 48 and 49 when said levers are rocked by the cam wheels 40 and 41.

-The levers 48 and 49 arieJ both pivoted Von the same pivot pin 50. Thepivot pin 50 is mounted in a standard 51, shown in Fig. 2 of the drawings as fiXedly mounted on the bed plate 42. As shown in Fig. 4 of the drawings, all the movements on the plane parallel t0 the bed plate 42 of the various levers and the platform 29 connected theref withare concentric with the pin 50. The shaft 26 and arm 16 are held substantially parallel to the lever 48, or in fixed angular relation thereto, by one arm of the lever 49, which is of the bell-crank type, and a .connecting link 52, which is pivotally attached to the free end of the lever 48by a pin 53, and with the platform 29, by a screw pin 54. The lever 49 is similarly connected by means of a screw pin 55, with the platform 29 at the point adjacent the forward end thereof, or at a `point proximate to the working position of the pen 14.

The cam wheel 40 functions through the lever 48 and the link 52 to oscillate the platform 29 and arm 16 connected therewith about the pin 55, to reciprocate the pen 14 in a relatively vertical path. If the platform 29 were'not reciprocatedlengthwise, the resultant of the operation of the cam wheel 40 and connections therewith, would be a vertical line performedby the pen 14, this line varying in accordance with the height .of the letters forming the writing be-k ing copied. The wheel 41 functions through the bell crank lever 49 to shift theplatform 29 and arm 16 lengthwise, swinging the same about the pin 50. rlhe operation of the wheel 41, if not affected by lthe operation of the wheel 40, would result in a transverse 1 or longitudinal mark equal to and regulated by the width of the letters forming the writing` being copied. By the combined actions of the cam wheels 40 and 41, the platform 29, arm 16 and pen 14, are moved' to obtain the combined result, forming by the pen 14, a letter having the contour or shape of the letter of the original.

The machine herein described and shown is designed principally for use in copying or executing signatures or fac-similes thereof.v

The necessary lateral feed of the table 29 and parts connected therewith is therefore somewhat limited, but whatever the feed or the travel of the table and pen 14 connected therewith, it is provided for by the shape of the cam wheel 41, the contour of which is arranged to provide for the feed of said platform by permitting one of the springs 56 to draw the power arm of said lever toward a shaft 57. The levers 48 and 49 are provided with pins 58 and 59, respectively, which pins bear upon the undulated edges of the cam wheels 40A and 41, being drawn thereto by the springs 56. The cam ^wheels 37, 40 and 41 are integrally constructed or rigidly connected. rl`he assembled wheels i are iXedly mounted on the shaft` 57. rlhe mechanism for reducing the speed of the',

armature shaft of an electric motor 66,

i which is employed asthe motive power in the present machine. The motor 66, shaft 65 and wheel 63 are continuously driven. The wheel 63 isloosely mounted on the shaft 62, and is furnished on one face thereof with a clutch tooth 67. Slidably mounted upon the shaft 62, and connected therewith, is a disk 68, which is furnished with a cam tooth 69, adapted to be engaged by the tooth 67. Normally the disk 68 is held away from the face of the wheel 63 by means of a coil spring 70. integrally connected with the disk 68 is a second disk 71, which is provided with a pin t2 extending from the face of the disk 71 in a-direction opposite to the extension of the tooth 6 9. The object of the pin 71, said shaft, worm, worm wheel and parts connected therewith are held stationary. These engagements are successive and, asfar as the engagement of the disks 71 and 73 is concerned, automatic. The initiation of this operation, or the engagement of the tooth 69A with the tooth 67 is manually efected.

' To start the machine, a handle 75 is engaged by the operator, said handle extending above the table 36 and through a slot 76 in a plate 77 mounted on said table. The y handle 75 is formed at the end of a vertically-disposed lever 78,- which lever is operatively connected with a shaft 79 supported in bearings upon .the bottom of the machine and extending to and rigidlyconnected with a rocking arm 80. The upper` end of the rocking arm 80 operatively engages the structure having the disks 68 and 71, and preferably a grooved collar disposed betweenv said disks. 'To engage the collar, the arm 8O is furnished with a yoke 81, the sides whereof have pins to enter the groove in said collar. The connecting mechanism between thelever 78 and the shaft 79 embodies a short pivot shaft 82, ,to which said I lever is rigidly connected, a link bar 83 and upright arms 84 and 85. It will be seen that by varying the lengths relatively, of

the arms 84 and 85, the movement,A of they disks 68 and 71 may be altered.

It will be noticed that a certain amountI of lost motion is provided in the operation of the arm 80 and disks 68 and 71, to pro-` 89, or create a partial rarefaction of the air in a vchamber 90 below said plate, the air being drawn lthence through a fduct 91. The pressure of the air thus imposed on a super'- posed sheet or piece ofpaper,.or other medium, holds the same in position during the subsequent movement of the pen 14 there over. To thus operate the valve 86, the lever 78 is provided with a cam-shaped tongue 92. As seen best in Fig. 1 of the drawings, the

, normal position of the tongue-92 is vthat where the end of the tongue rests against the side of the lever 93 provided for operating the valve 86.. As seen best in Fig. 3 of the drawings, the arm 85 is extended below the shaft 79, while the arm 84 is extended above the shaft 82. In this manner, there is imparted to the shaft 79 a rotation which carries the disks 68 and 71 toward the wheel 63 when the handle 75 of the lever 78 is moved away from the position indicated by the word Stop on the plate 77 toward the positions indicated successively by the words On and Start In this portion ofthe movement of. the handlev 75, to wit, that which roximates saidhandle with the word n, the valve 86 is opened to permit the fan to\iraw the air from the chamber 90. At this time, and until in the further movement of the handle 75, said handle reaches the word Start, .the disk 68 has'.

not engaged the wheel v63, and therefore the pen 14 remains stationary and liftedv from the-paper or the plate 89. l.

The operator holdsthe handlev 75 .opposite the position Start until the tooth 69 i' on the disk 68 is engaged bythe tooth 67 on the wheel 63'. The irst part of the-Inove--' ment now impartedto the shaft 62 carries' the pin 72 away from the perforation in the disk 73.

The operator now releasing the 4 handle 75, the vpin 72 operates to maintain the engagement'of the teeth 67 and 69, said pin riding on the face of the stationary disk 73. When, inthe course offits travel, the.l

pin 72fregi'sters with; said perforation 1in the disk 73, this lpinenters said perforation,

being forced therein by the spring 70. The arm 80 and the shafts 79 and 82 vare simul ltaneously rocked back to their normal posil v tionas illustrated in-Fig. 1 of thedrawings,

where the handle 75 is arrested lopposite the station designated by thev .word Stop Any suitable spring4 is employedto hold the lever 93 ofthe valve'f86 lin engagement Operation-With a. machine` structed and' arranged, the .operationisl as*` follows :'-The undulations Ajon the earn wheel 37 provide a surfacewherethe .roller-38j ton.

plate 89.- l Thisl permits-the introduction un# der the point of the pen, of theA paper-or vthe arm 39 is-.so disposed' thatche-fshafti'ls. vis rocked to lift. thezp'en 14 from the face l medium ,upon whichfthe signature "orfa04 Simile is mbe inscribed. #This having beenV done bythe operator,he' n1oves' thehandle 75 `on 'thelever 578' to the position indicated by'the word ,On., 'The motor66, as above explained,l isv continuouslyl running. ALikes wise, the fan in the. casing.,8'7, and the'wh'eel. 63, arev continuously operatingMand .are lin nowise dependent upon'thelmovement of the handle 75. The valve ,86 preliminarily opened, and thel suction produced' :by vthe. operation ofl the fan under 'thel face plate 89 ,operates to fix in position the paper or medium disposed :onv ,saidV lpla-te. In this position, the disks68 and 71 are disengaged' from the disk 73, or not engage'djwith thel wheel 63'. This last engagement isnow effected by the'further' movementof the handie, L7 5 to opposite the station designated by the word Start'. f

This Vmovement ofthe handle 75A correspondingly moves the'tbth 69 ofI the disk 68 into the path -of the tooth 67 on the,continuouslyfrunningf-wheel 63. As explained,` .the preliminary stage of the ias rotation of the disks 68 and 71 places the", pin 72 in riding position on the stationary disk 73, thereby permitting the .operator to release4 the-handle 75, which is held there:

,after by said pin '72, `until the same is in correspondence with the shape or contour.

of the undulating edges. At the initiation of the rotation of the wheel 37, the arm 39 is lifted to lower the point of the pen 14 to rest on the paper held on the plate 89. The undulations provided on the raised edge of the wheel 37, now and throughout the operation, rock the shaft 18 to increase or diminish the pressure on the point of the pen 14 in simulation of the idiosyncrasies of the original writer of the signature or inscription being duplicated. The contour of this edge provides that if the signature has two names or a space between words, where` no markings areeffected, the pen 14 is lifted from engagement with the paper by the rocking of the shaft 18 in correspondence with the work being performed. Cordinate with the operation of the cam wheel 37, the cam wheel 40 oscillates the pen 14 in a vertical path, and the cam wheel 41 functions to oscillate and move the pen point laterally, and to feed the same longitudinally over the plate 89 and paper lheld thereon. rIhe result of the correlated operations of the cam wheels 40 and41 is a tracing having all of the idiosyncrasies of the original copy, while the characteristics or idiosyncrasies of pressure have been impartedthereto by the opera-tion of the cam wheel 37. To assist in operatingthe shaft-18, the retracting spring 94.is provided, being connected to' and eX- tending between the platform 29 and the connecting rod 24, as best shown in Fig. 2 of the drawings. r' f At: the completion lof the signature, the cam wheel 37 provides for elevating the pen 14 from the paper during the continuation of the operation. It will be understood that fthe machine provides for a maximum length of signature or inscription, and that therefore the feed of the cam wheel 41 continues, irrespective of the varying length of said signatures, or until the pin 72 falls into the `perforation provided in the disk 73, when the spring 70 shifts the disks 68 and 71 and parts connected therewith to release the shaft 62 and hold the cam wheels against further operation of the pen 14 and holder 13 thereof. The handle 7 5 and lever 78 being returned to their original positions, the valve 86 is closed. The closing of said valve restores the air pressure in the chamber 90 beneath the plate 89 and the paper disposed thereon, thus permitting the removal of said paper having the mechanically-inscribed signature imparted thereto.
